12.4 Implements, Tools & Abrasives
Key Takeaways
- Grit is the number of abrasive particles per square inch, so a lower number is a coarser, more aggressive abrasive; nothing coarser than about 180 grit should touch the natural nail plate.
- Grits below 180 are for reducing enhancement product, 180 to 240 for shaping enhancements, 240 to 600 for finishing and natural nail work, and above 600 for buffing and shine.
- The natural free edge is filed from the outside corner toward the centre in one direction; sawing back and forth separates keratin layers and causes splitting.
- Ohio classifies implements by porosity: non-porous items are cleaned then completely immersed in an appropriate disinfectant, while porous items are discarded after each client.
- Natural-bristle brushes are single use in Ohio under OAC 4713-15-03(B), while synthetic-bristle brushes may be reused if properly disinfected before each use under OAC 4713-15-09(A).
Implements, Tools and Abrasives
Ohio State Board Exam Alert: "Tools/Implements" is a leaf inside the 5 % Implements, Tools & Equipment domain, and "tools and equipment" is a subject in the Nail Care block of Ohio's 200-hour curriculum. The Board's practical examination scores "implements/tools are visibly clean" in both the set-up and the tip tasks. This is a small domain by weight and an unforgiving one in practice.
1. Professional Implements & Materials: Multi-Use vs. Single-Use
Under Ohio infection control standards, every tool, supply, and cosmetic substance utilized during a manicure falls into one of three distinct regulatory classifications:
| Classification | Definition & Material Composition | Regulatory & Sanitary Handling | Salon Examples |
|---|---|---|---|
| Multi-Use Implements | Non-porous tools constructed of stainless steel, hard plastic, or glass capable of undergoing complete decontamination. | Must be washed with soap and warm water, scrubbed with a clean brush, completely submerged in an EPA-registered hospital disinfectant for the full contact time, dried, and stored in a clean, closed container. | Metal cuticle pushers, cuticle nippers, nail clippers, tweezers, glass files. |
| Single-Use Disposables | Porous, fibrous, or absorbent items constructed of wood, paper, cotton, or foam that cannot be safely disinfected. | Used on exactly ONE client and immediately discarded into a closed, foot-pedal waste receptacle; never saved, sanitized, or reused. | Wooden orange sticks, emery boards, buffer blocks, cotton pads, lint-free gauze wipes, toe separators. |
| Professional Products & Cosmetics | Liquids, gels, creams, and powders used to cleanse, condition, and coat natural nails. | Dispensed hygienically using pump dispensers, droppers, or clean spatulas; containers must be tightly closed and labeled; never touch skin with droppers. | Polish removers, cuticle removers, nail dehydrators, cuticle oils, lotions, base/top coats. |
Multi-Use Metal Implements
- Stainless Steel Cuticle Pusher: Features a contoured, spoon-shaped end designed to mirror the natural curve of the nail matrix and eponychium, and a flat or beveled scraping edge. Used to gently loosen and scrape away non-living cuticle tissue adhering firmly to the dorsal nail plate. Must always be held flat against the nail plate at a 45-degree angle to avoid gouging or denting the fragile nail matrix.
- Cuticle Nippers: Precision stainless steel cutting tools featuring two sharp, angled cutting jaws controlled by a single or double-spring lap joint or box joint. Designed exclusively for trimming loose, non-living hangnails or ragged tags of dead skin. STRICT RULE: Cuticle nippers must never be used to cut, trim, or slice the living eponychium or live lateral nail folds!
- Nail Clippers: Heavy-duty cutting implements with curved or straight blades used to shorten natural fingernails quickly and safely before filing. Clippers must be operated with controlled, small snips starting from one lateral edge toward the center, never chopping across the entire width of the nail in a single squeeze, which can crack the keratin plate.
- Tweezers: Fine-pointed stainless steel tweezers utilized to retrieve tiny debris, lift nail art decals, or grasp sterile cotton pellets without contaminating the primary workstation.
Single-Use Disposable Supplies
- Wooden Orange Wood Sticks: Slender wooden sticks featuring a flat, beveled edge on one end and a pointed tip on the other. Used to apply cuticle remover, gently loosen dead cuticle, clean under the free edge (subungual space), or remove accidental polish smudges from the periungual skin. To enhance safety, the tip can be wrapped in a tiny wisps of sterile cotton.
- Abrasive Files & Emery Boards: Graded by the number of abrasive particles per square inch (grit rating). The lower the grit number, the coarser and more aggressive the abrasive action:
- Coarse Grit (under 150 grit): Extremely aggressive; reserved exclusively for artificial nail enhancements (acrylics and hard gels). NEVER use coarse abrasives on natural nails, as they shred natural keratin fibers and cause severe thinning.
- Medium Grit (180 to 240 grit): The industry standard for shortening, shaping, and refining natural nail free edges. Smooths edges cleanly without causing traumatic splintering.
- Fine Grit (240 to 400 grit): Used for gentle surface smoothing, beveling the free edge, and preparing natural nail plates for enhancement or gel application without removing structural layers.
- Buffers (400 to 1,200+ grit / 2-way and 3-way buffers): Ultra-fine abrasive blocks or pads designed to buff out surface ridges and create a mirror-like natural glossy shine without requiring lacquer.
Professional Cosmetics & Chemical Preparations
- Nail Polish Removers:
- Acetone Removers: Highly effective polar solvent that rapidly dissolves nitrocellulose lacquer resins, gel coatings, and acrylics. Highly drying to natural skin and keratin lipids; best reserved for dark, heavily pigmented lacquers or fast removal.
- Non-Acetone Removers (Ethyl Acetate or Methyl Ethyl Ketone): Milder solvents that dissolve traditional lacquer more slowly without softening or deteriorating artificial nail enhancements (such as silk wraps or acrylic overlays). Recommended for clients with sensitive skin or artificial overlays.
- Cuticle Removers: Highly alkaline formulations typically containing 2% to 5% potassium hydroxide (KOH) or sodium hydroxide (NaOH), supplemented with moisturizing glycerin. These alkaline agents rapidly break down the disulfide bonds and keratohyalin proteins of dead cuticle tissue adhering to the nail plate, allowing it to be scraped away effortlessly. Because of their caustic alkalinity, cuticle removers must be neutralized and completely rinsed off with clean water after 2 to 3 minutes to prevent chemical burns on surrounding living skin.
- Nail Bleach (Lightener): Formulated with mild 3% to 6% hydrogen peroxide or organic acids, designed to remove yellow nicotine stains, cosmetic pigment discolorations, or environmental dullness from the natural nail plate.
- Cuticle Oils & Conditioners: Nutrient-rich formulations containing lightweight vegetable and botanical oils—such as jojoba oil, sweet almond oil, safflower oil, and Vitamin E (tocopherol). Jojoba oil possesses a molecular size and wax ester composition remarkably similar to human sebum, allowing it to penetrate through the microscopic interstitial spaces between keratin layers to restore nail plate elasticity and prevent brittle cracking.
2. Abrasives: Grit, Selection and Damage Control
Abrasives are graded by grit, the number of abrasive particles per square inch of the surface. The relationship is inverse and counter-intuitive to beginners: a lower grit number means larger, coarser particles and a more aggressive abrasive; a higher number means finer particles and a gentler action.
| Grit range | Class | Correct use |
|---|---|---|
| Below 180 | Coarse | Reducing the length and thickness of enhancement product only. Never on the natural nail plate |
| 180–240 | Medium | Shaping and refining enhancements; the coarsest that should approach a natural free edge |
| 240–600 | Fine | Finishing enhancements; gently shaping and smoothing the natural nail |
| Above 600 | Buffers / shiners | Removing shine before product, and producing a high-gloss natural finish |
Rules that follow from the grit table:
- Nothing coarser than 180 grit touches the natural nail plate. A coarse abrasive removes keratin layers, thins the plate and creates the ridges and weakness clients blame on the product.
- File the natural free edge from the outside corner toward the centre, in one direction. The Ohio practical scores "shapes free edge from corner to center safely." Sawing back and forth separates the keratin layers and causes splitting and peeling.
- Buffing before product removes shine only, not layers. The examination phrase is "shine is removed from nail plate" — a light pass, not an excavation.
- Match the abrasive to the material. Enhancement product is harder than natural keratin; a grit chosen for acrylic will destroy a natural plate.
Multi-use implements versus single-use items
Ohio decides this on porosity, not on cost or appearance.
| Category | Ohio treatment | Examples |
|---|---|---|
| Non-porous, multi-use | Clean with soapy or detergent water, then completely immerse in an appropriate disinfectant in a clean covered container before use on a new patron (OAC 4713-15-03(A)(1)) | Metal pushers, nippers, cuticle nippers, tweezers, metal files, glass files, stainless bowls |
| Porous, single-use | Discarded after each client; may not be cleaned or disinfected for reuse (OAC 4713-15-03(B) — a published FY2025 top-ten violation) | Natural-bristle brushes, wooden pushers, cotton, gauze, disposable files and buffers, toe separators, sanding bands, orangewood sticks |
| Synthetic brushes | May be reused, but must be properly disinfected before each use in accordance with OAC 4713-15-03 (see OAC 4713-15-09(A)) | Nylon dusting brushes, application brushes |
The line to remember: natural bristles are single use in Ohio; synthetic bristles may be disinfected and reused. That one sentence covers a rule the Board cites often enough to publish it in its annual report.
Storage closes the loop. OAC 4713-15-03(E) requires unused porous items and disinfected implements to be stored in a sealed, dustproof container, and OAC 4713-15-01 requires used or unclean equipment to be "stored separate and apart from clean items." Two labelled containers — clean and soiled — at every station is the practical implementation.
A technician reaches for a 100-grit file to shape a client's natural free edge because it will be faster. What is wrong with that choice?
